Methods and systems for authenticating users based on contextual data in a privacy preserving way are disclosed.
Claims21
A method to secure a user's interaction with a remotely accessible computer-based application, the method comprising the steps of:
- collecting one or more sets of contextual data;
- anonymizing the collected one or more sets of contextual data;
- transferring the anonymized contextual data sets to an authentication server;
- at the authentication server analyzing the received anonymized contextual data sets for authenticating the user;
- wherein the one or more sets of contextual data comprise values of one or more computable contextual data elements;
- wherein the step of anonymizing the collected one or more sets of contextual data comprises transforming a first value of at least one of said computable contextual data elements using a similarity preserving anonymization transformation.
